I have a farmall b and trying to finish converting to 12v that someone else started. I have a 10SI (3 wire)alternator. the wire from the batt. Terminal on it runs to a ammeter then it comes off the ammeter to the starter switch (10 guage wire) located on the starter itself, then I have a wire (2 guage i beleive) going from their to the positive battery terminal. Now I also have a 12 guage wire with a diode going from ammeter back to alternator on the #2 terminal to excite it. My problem is I charge the battery and the next day it is dead. I haven't used it in the field yet, still trying to figure this problem out, battery is only year old and holds charge when off the tractor and alternator tested good from autoparts store.
